iis security : both anonymous AND windows integrated auth... what is the precedence

Hi. I am troubleshooting a problem at a customer site. I have never mixed
authentication on servers so I do not know what is supposed to happen. If I
have a server with a site that has anonymous AND windows integrated auth set
up, and a person hits a web page on that site, whose credentials are used?
Could it be that the windows integrated auth takes precedence over
anonymous?

Thanks

This explains the order of precedence:

Anonymous will be tried first - unless the user has already authenticated.

Hi Stephanie,

AFAIK anonymous is used first. If Anonymous can't be used (IUSR doesn't have
necessary permissions) it will try Integrated Authentication (if IIS allows
it). If Anonymous is not allowed and e.g. basic and integrated
authentication is selected, then first more secure authentication is used
(in above case IA) followed by less secure (in above case basic auth).
